SLEJ).

To-aZZ whom t may concer/n.'

Be it known that I, SIDNEY S. GRIHIN, a citizen of the United States ofAmerica, residing at Tacoma, in the county of Pierce and State ofWashington, have invented certain new and useful Improvements in Sleds,

4of which the following is a specification.`

This invention relates to sleds and more particularly to dirigible'sleds and its object is to provide simple and inexpensive means wherebythe occupant of the sled WlllY be enabled to eiiciently guide'or steerthe same by hand. l

A further object of the invention is to provide a front truck or sledconstructed in such manner that the opposite sides thereof may beshifted to varying positions of angularity with respect to the body ofthe sled while being maintained in parallelism with each other and atthe same time will be securely braced with respect to each otherthroughout varying positions of adjustment.

Further objectsand advantages of the invention will be set forth in thedetailed description which now follows:

In the accompanying drawing,

Figure 1 is a side elevation of a sled constructed in accordance withthe invention.

Fig. 2 is a transverse, vertical section upon an enarged scale and uponline 2-2 of Fig. 2, an

Fig. 3 is an enlarged plan of a part of the front truck of the sled, thebody of the sled being removed.

Like numerals designate corresponding parts in all of the figures of thedrawing.

, Referring to the drawing, 5 designates the body of the sled, 6 a rearbolster secured to the body by fastening devices 7, and 8 the reartruck, which rear truck is cured to the bolster 6 by the same fasteningdevices that secure the bolster 6 to the body 5. A front bolster 9 issecured to the body 5 by bolts 10. The front truck indicated in ageneral way at 11 comprises runners l2 and 13. each of said runnerscomprising a top rail 14, a bottom rail 15 and a curved connectingportion 16. Vertical braces 17 and 18 extend between the rails 14 and 15and these braces between their'ends are bent to form U shaped portions19 within which the opposite ends of cross links 20 and 21 are pivoted.These cross links are centrally pierced at 22 for the reception of theopposite ends 23 and 24 of the horizontal mem- `Specification of LettersPatent.

railslc of lthe runners are pivotally connected to the bolster bybolts29 and it will, therefore, be seen that each ofthe front runners swingsaround one of the bolts 29 as a center and that these runnersmay beactuated to thus swing around said bolts by the manipulation of the handwheel 26 because the turning-.of the hand wheel 26 and its shank 25throws the links 20 andA 21 in opposite directions and moves the frontrunners to varyin positions of angularity with respect to the ody 5while at the same time the parallelim of these runners is maintained.Furthermore, the links 20 and 21 extending between the braces of thefront runners act themselves as braces to maintain the desired rigidityof the structure as a whole.

It will, therefore, be seen that the present invention comprises lverysimple and inexpensive means w'hereby it is possible to steer a sled byhand and with the occupant sitting upright thereon, if desired.` Itwill. also be seen that the elements designed to accomplish theforegoing object have been correlated in such a novel manner as to bracePatented Aug. 2e, 1917.

truck.

Having described my invention what I claim is 1. A device of thecharacter described comprising a body portion, a truck comprising a pairof runners, each of said runners comprising-top and bottom rails andvertical braces, means for pivotally connecting the top rail of eachrunner at a point intermc` diate its ends to the body portion, a pair oflinks extending laterally between said rails and having4 their oppositeends pivotally connected to the braces of the runners, said links lyingupon opposite sides of the pivotal connection of the top rails of therunners with the body portion, a T' shaped steering member comprising avertical shank passing through the body portion and a horizontal lowerend, the extremities of which engage said links. f

2. A truck or sled comprising a pair of runners, each of saidrunnerscomprising top and bottom rails, vertical braces extendingbetween the top and bottom rails, each of said braces having outwardlybent shaped portions7 links extending between the oppo site braces ofthe runners and having their ends pvoted in said U shaped portions and amanually operable member engaging said links.
